When you sell a content site you have three routes: list it yourself on a marketplace, sell it privately to a buyer you already know, or hire a website broker to run the sale for you. The broker route costs the most in headline terms, so the question is what you get for the fee and when that trade makes sense. This post sets out how broker fees are structured, what the work involves, and the clauses to read before you sign anything.
How a website broker gets paid
Most brokerage agreements are built around a success fee. The clearest definition we found comes from WebsiteClosers, which is itself a broker, so read it as a seller of the service describing its own model. Its guide, What Is A Success Fee In A Business Sale by E. Doug Grindstaff III (updated 29 June 2026), puts it this way: “A success fee is the commission paid to a business broker or M&A advisor upon the successful closing of a deal.”
The fee is performance-based and normally comes out of the final purchase price. It is not a flat or hourly charge. If the sale does not close, the success fee is not paid, which aligns the broker’s incentive with yours, at least on the question of whether a deal happens at all.
On the size of the fee, the same guide is careful: “There’s no fixed number, but most success fees fall between 5% and 15% depending on the deal size.” That range is wide on purpose. Smaller deals sit at the top of it, because the work of preparing and marketing a sale does not shrink in proportion to the price.
Tiered fees and the Lehman Formula
Larger deals are often priced on a sliding scale. Tiered models such as the Lehman Formula, and its variant the Double Lehman, “reduce percentage rates as the total deal size increases”. The guide gives a sample tier, set out below. It is an illustration from that article, not a rate any particular broker charges.
| Fee element | What the WebsiteClosers guide says | What to check in your agreement |
|---|---|---|
| Success fee | Paid on successful closing, typically from the final purchase price | Whether “closing” includes deferred or earn-out payments |
| Typical range | “most success fees fall between 5% and 15% depending on the deal size” | Where your expected price sits in that range |
| Sample tier, first $1 million | 10% | The exact breakpoints, in writing |
| Sample tier, next $2 million | 8% | Whether tiers apply to the whole price or only the slice |
| Sample tier, above $3 million | 5% | Any minimum fee that overrides the tiers |
| Upfront costs | “Nothing is charged upfront unless the agreement includes a separate retainer or marketing fee” | Whether a retainer is refundable or credited against the success fee |
Upfront fees, retainers and what the broker does
The no-upfront-fee model is not universal. Some brokers charge before the sale for valuation, packaging or marketing, and the guide notes that a small upfront fee plus a larger success fee is a common arrangement. Neither model is wrong. A retainer screens out sellers who are not serious; a pure success fee pushes all the risk onto the broker. What matters is that you know which one you are signing and what the upfront money buys.
The work itself is not trivial. In the guide’s words, “Most brokers spend weeks or months preparing materials, sourcing buyers, and running calls.” Beyond that they manage offers, negotiate, run the due diligence process and see the deal through to closing. For a seller with a full-time business to run, that time is the main thing the fee pays for.
Broker, marketplace or private sale
The website brokerage model sits between two cheaper options. Open marketplaces such as Flippa let anyone list, and you handle the buyers yourself. Curated marketplaces such as Empire Flippers and Motion Invest vet listings and bring a buyer pool, but you still prepare much of the material. Advisory firms such as FE International and Quiet Light work closer to a traditional broker. We are not quoting any of their commission rates here; check each one’s current terms directly.
A private sale, to a competitor or a buyer who has approached you, costs nothing in fees but leaves you doing every step, including pricing, contracts and escrow. Our guide on how to sell a website walks through those steps if you go it alone.
When the fee is worth paying
In our judgement, a broker earns the fee in three situations. The first is a larger site, where a few percentage points of a better price outweigh the commission. The second is a clean site, with tidy books and verifiable traffic, which a broker can take to serious buyers quickly. The third is a seller whose time is worth more than the fee, because running buyer calls and due diligence for weeks is real work.
The fee is harder to justify on a small site, where the percentage is highest and the buyer pool is the same one you could reach on a marketplace. Before you approach anyone, get a realistic sense of value from our post on how much a website is worth, so you can tell whether a broker’s valuation is grounded or flattering.
Questions to ask before you sign
The best website broker for you is the one whose terms you fully understand. The guide suggests asking for testimonials and previous case studies, and benchmarking rates against brokers who serve businesses of your size. Beyond that, these are the questions we would put to any broker before signing:
- Is there any upfront fee, and is it credited against the success fee if the sale closes?
- Is there a minimum fee, and at what sale price does it override the percentage?
- How long is the exclusivity period, and how do you end it early?
- If a buyer I found myself closes the deal, does the full fee still apply?
- Does the fee apply to earn-outs and deferred payments, and when is it due on them?
- Which recent sales of comparable size can you point to?
The buyer-you-found clause catches sellers most often. If you already have an interested party, name them in the agreement or exclude them, otherwise you may pay full commission on a sale you sourced. Buyers will run their own checks too, so read our website due diligence checklist and fix what it would flag before the broker starts marketing.
The limitation here is the source. The fee figures come from one guide written by a broker, which describes the market in general terms. It does not tell you what any named broker charges today, how often fees are negotiated down, or how sale prices compare between brokered and self-run deals. Treat the 5% to 15% range as a starting point for the conversation, not a quote, and get every number in writing. If you are on the other side of the deal, our post on buying a site covers the research to do before you bid on a brokered listing.
Frequently asked questions
How much does a website broker charge?
Usually a success fee taken from the sale price at closing. A broker-written guide from WebsiteClosers says most fall between 5% and 15%, depending on deal size.
Do website brokers charge upfront?
Some do, for valuation, packaging or marketing. Others charge nothing until closing. A small upfront fee plus a larger success fee is common.
What is the Lehman Formula?
A tiered fee where the percentage falls as the deal grows. One sample tier is 10% on the first $1 million, 8% on the next $2 million and 5% above that.
Is a broker better than a marketplace?
For larger, clean sites, or sellers short on time, often yes. For small sites, a marketplace usually reaches the same buyers for less.
The takeaway A website broker earns a success fee at closing, typically 5% to 15%. Pay it for larger, clean sites or when your time is scarce, and read the upfront, minimum and exclusivity terms first.
